I HAVE PURCHASED APPROX 10 SET OF THESE RETRACTS AND STILL HAVE PROBLEMS WITH LOTS OF THEM. HAS ANYONE CAME UP WITH A WAY TO MAKE THE GEAR FASTER? HAS ANYONE FOUND A SUPPLIER THAT YOU CAN CHANGE OUT THE SHAFTS WHEN THEY BREAK? CAN ANYONE TELL ME HOW TO STOP THE GLITCHES? I HAVE BURN OUT 6 SERVOS DUE TO THE GEAR GLITCHING, IS THERE A WAY TO STOP THIS? THESE GEAR WILL NOT WORK WITH MY DOOR SEQUENCIER, DOES ANYONE KNOW ONE THAT WILL WORK WITH THE SYSTEM? I REALLY LIKE ELECTRIC GEAR OVER AIR, BUT ANY HELP TO RESOLVE MY PROBLEMS WOULD BE APPRICATED.
